DM-900 Site Monitor

The DM-900 Site Monitor is a highly sophisticated stand alone product that
delivers quality monitoring at a reasonable price. The DM-900 has eight inputs that can be configured for contact closure or voltage alarms. These inputs can be configured as Alarm, Event, or Normal for both the Normally Closed and Normally Open conditions. Using any of the back haul options, this product can deliver alarms to an alphanumeric pager or a PC located at a Network Operations Center (NOC).

The DM-900 has a built in photocell monitor that works with 110VAC photocells and has selectable day / night alarm timers and logs when the photocell changes from day to night and back to day. The cabinet door is monitored and can be used to generate an alarm for quarterly tests or for tamper detection. When there is a power loss an on board circuit monitors the battery discharge, disconnecting it before damage occurs to the backup battery.

The DM-900 can be interrogated using either terminal emulation software or the
optional Windows compatible PC software.  With this interface the alarm conditions you set can be viewed and logged at any time.  Reports can be generated from the logged data on a per site basis.
